I'm trying to understand the difference between an iSCSI and a network share. So I've got a NAS device on the network.
When i use a network share, the computer knows that the location is remote. While, when i have an iSCSI target connected, the computer thinks that the target is another Hard Disk that is physically connected to itself. kewl - i get all that.
What I don't understand is the next bit. When i connect the iSCSI target.. my computer sees the new Hard Disk and wants me to format it. er.... waa???????? format it? But its already formatted! and i have data on it already .. just connect to the share and have a look in there.
So that's what I don't understand. Why do we need to format the disk when it's already formatted? If i format it, what will happen with the size of the other stuff? and the existing data?
I understand that, when u create an iSCSI target, u specify the size. So what happens if i specify more size than is free? (eg. we have existing data, remember).....
FWIW, the NAS is a Synology DS211.
